Title: Dimming circuit for stroboscope
Inventor: HARADA YOSHIHITO
IPC: H05B41/32
Filed: 1993-04-13
Abstract: PURPOSE:To prevent a fault in dimming accuracy caused by leakage and to reduce the number of IC pins by incorporating a photosensor for the dimming of a stroboscope and an integration capacitor in an IC chip. CONSTITUTION:This dimming circuit for the stroboscope is costituted to incorporate the photosensor D1 and the integration capacitor C1 in an IC. In the circuit which is obtained by connecting a resistance R1 functioning as a current/voltage converting element and a MOS switch Q4 in series is juxtaposed in parallel with the capacitor C1. In order to monitor the potential of the C1 which is changed, the operational amplifier AMP2 of a MOS top is put and buffered so as to observe the potential from an (h)-terminal. Thus, measurement is performed by making an (f)-terminal low and a (g)-terminal high after giving normal light to the photosensor D1 and making a photoelectric current i1 constant. By making the (g)-terminal high, the Q4 is turned on, and by making the resistance value of the Q4 on-resistance which is lower than that of the R1, the potential of VH-R1Xi2 is monitored from the (h)-terminal.

Title: Field-effect semiconductor device
Inventor: SHIODA MASAHIRO
IPC: H01L21/338
Filed: 1987-04-08
Abstract: PURPOSE:To eliminate P.P.C. (Persistent Photoconductivity) and to improve mutual conductance gm of a field effect semiconductor device by laminating a spacer layer made of non-doped AlGaAs between an electron supply layer made of Si-doped GaAs and an electron transit layer. CONSTITUTION:An electron supply layer 9 made of Si-doped GaAs, an electron transit layer 7 made of InGaAs, and a spacer 3 made of non-doped AlGaAs interposed between the layers 9 and 7 are laminated between a gate electrode 6 and a compound semiconductor substrate 1. Since the layer 9 uses Si-doped GaAs having no D-X sensor as the layer 9, the temperature change of a threshold value voltage Vth is less, P.P.C is eliminated, and since the non-doped AlGaAs layer is used as the layer 3, a discontinuity to a conduction band to the InGaAs of the layer 7 can be increased to be able to increase the sheet carrier concentration of secondary electron gas, thereby improving gm.

Title: Magnetic transfer method
Inventor: YAMASHITA KEITARO
IPC: G11B5/86
Filed: 1994-04-25
Abstract: PURPOSE:To eliminate the need of special frequency characteristics for dealing with the deterioration thereof due to the field transfer at the time of recording on a mother magnetic recording medium. CONSTITUTION:The coil in a transfer bias field head is fed with an AC current, corresponding to an oscillation signal from an oscillator, from an amplifier and a transfer bias field is applied to a part where a mother tape MT touches a copy tape CT thus transferring a recorded content from the tape MT to the tape CT. The strength of transfer bias field is then varied sequentially and the frequency of signal to be recorded on the tape MT is changed sequentially among a plurality of types of frequency for each strength of transfer bias field thus transferring the recorded content from the tape MT to the tape CT. The reproduced output level of the CT tape is then measured in order to determine the transfer frequency characteristics for each strength of transfer bias field. A strength of transfer bias field for obtaining optimal transfer characteristics, i.e., the transfer frequency characteristics substantially identical to those for head recording, is then selected based on the transfer frequency characteristics thus determined.

Abstract: PROBLEM TO BE SOLVED: To obtain a medicine release-control type percutaneous absorptive formulation freely controlling releasing rate of a medicine according to an object of curing, having exceedingly excellent storage stability and high safety without inducing a rush by pasting. SOLUTION: A microcapsule comprising a water-soluble wall material including a medicine and a water-insoluble, rubber and rubber solvent-insoluble water-absorptive resin powder (e.g.; starch-polyacrylate graft copolymer) are mixed and dispersed in a rubber-based tacky adhesive. The rubber-based tacky adhesive is mainly composed of a rubber-adhesive component (e.g.; isoprene-based rubber), a tackiness-imparting agent (e.g.; a petroleum resin) and a plasticizer (e.g.; a liquid paraffin). An oily substance not dissolving the wall material is used as the medicine and the wall material is selected from a water-soluble polymer such as gelatin. By microcapsulating the medicine and an absorption accelerator, storage stability of the formulation is high and body fluid is absorbed into ointment by pasting on the skin, then the medicine and the absorption accelerator are eluted by slowly destructing the microcapsule, thereby a medicine release can be controlled by mixing several kinds of microcapsules having different membrane thickness.

IPC: G06F12/12
Filed: 1991-03-27
Abstract: PURPOSE:To improve the processing performance of a date base control system by reducing the data input/output frequency in a data base control process. CONSTITUTION:A resident parameter is received at a parameter transfer area 2 from the outside and describes a fact that at least a part of a data base file 6 is resident to a large capacity data buffer and that the residence of the file 6 is canceled. The contents of the parameter received at the area 2 are analyzed by a resident parameter analyzing means 3. A residence control means 4 performs the transfer of the parameter between the buffer 5 and the file 6 with a parameter describing instruction. Therefore the residence of the file date is attained to the buffer 5 or this residence is canceled by the resident parameter. Thus the resident parameter can perform the control. to reduce the date input/output frequency.

Title: Beam type safety device for machine tool
Inventor: KOMORI TAKEHIKO
IPC: B30B15/00
Filed: 1989-04-10
Abstract: PURPOSE:To enable the operation of a machine tool during the operation of a safety device even in an optical axis interrupted due to a long work-piece by providing a means for detecting and saving an interrupted optical axis prior to machining, and another means for outputting an optical axis interruption signal in the case of the interruption of an optical axis other than the saved axis data. CONSTITUTION:A synchronous signal generation part 6 generates a synchronous signal at the predetermined intervals. A select signal generation part 9 outputs the predetermined select signal to an optical axis data memory part 7, a multiplexer 8, a data comparison part 10 and a multiplexer 11, in response to the aforesaid synchronous signal. When the optical axis select signal does not agree to the output data of a decoder 12 after comparison in the data comparison part 10, it is judged that the predetermined optical axis among axes formed between a projector 1 and a light receiving unit 2 is interrupted, and the data comparison part 10 outputs an optical axis interruption signal. A mode judgement part 16 makes judgement as to whether the current mode is a normal light interruption mode or a multi-optical axis interruption mode on the basis of a mode setting pulse signal outputted from a setting switch 13.
